8 Port Underfloor Heating Manifold – Nickel-Plated Brass 8 Circuit Kit with Flow Meters, Automatic Air Vent, Pressure Gauge & Drain Valves

This 8 port nickel-plated brass underfloor heating manifold distributes heated water to 8 underfloor heating circuits, ideal for a large floor or whole house. It comes as a complete kit with flow meters, automatic air vent, pressure gauge, drain valves and wall brackets, pre-mounted and ready to fit.

The flow meters double as isolating and balancing valves, and every return valve accepts an electro thermal actuator for room by room control. Covered by a 5 year warranty*.

Installation and compatibility

Connect pipe with eurocone couplers sized to your pipe, for example 16×2 eurocone couplers, and fit 230V actuators or 24V actuators for zone control. Add a pump and mixing set from our pump and blending set range.

Not sure what size you need? Use one port per circuit, and read our ultimate guide to underfloor heating manifolds, where to place a manifold and brass vs stainless steel manifolds. See the full manifold range.

*To qualify for the 5 year warranty, existing systems must be power flushed before the underfloor heating is connected, and inhibitor must be used to prevent corrosion.

Frequently asked questions

What comes with the UFH Direct manifold kit?

Flow meters, automatic air vent, pressure gauge, drain valves and wall brackets, all pre-mounted on the flow and return bars.

Will the manifold work with my actuators?

Each return valve accepts an electro thermal actuator with a stroke of 3mm or more, such as our M30 x 1.5mm actuators.

How many ports do I need?

One port per underfloor heating circuit. Larger rooms often need more than one circuit.
